Seals were often made of stone however there are also examples rendered in bone, ivory, faience, glass, metal, wood, and even sun-dried or baked clay. Seal amulets with stylised animals have been found throughout Mesopotamia in contexts dating to the late fourth millennium BC, although stamp seals and cylinder seals were the predominant types in the ancient Near East.
